GLASS-TBLGWING aaacsznn.

Application filed April 27, 1907.

My invention relates to that class of glass blowing machines which areadapted to receive a bl ow-pipe on which the gl ass has been gatheredand has received such preliminary treatment as may be necessary. andwhich are provided with mechanism actuated by the movement of themachine, for closing the molds. for imparting rotary motion to theblow-pipes in respect to the molds, for open ing the molds, and foradmitting air under pressure to the interior of the article to be mentcoinciding blown at such times as it -may be necessary.

For this purpose it consists oil. an organization of such a machine inwhich the molds travel in a vertical plane. the lower part of the pathoi the molds being utilized to dip' them in water and the upper part. oftheir path being that in which the molds are closed; and in which theblow-pipes travel in a horizontal plane, their path of movetor a certaindistance with the path of the molds. This efiected by pl acing' the mohls upon an apron carried by horizontalv shafts whereby a straight runis provided for the molds above such shafts, while the blow-pipes areadapted to be received by an apron carried by vertical shafts. a part oithe run of the blow-pipcs carried by the apron being located above theupper run ol the m lds. llith the 1nold-apron is associated mechanism'l'or automatically closing the molds at the commencement oi their upperrun and for aute'imatically opening them at the termination oi theirupper run. while with the hlow-pipe apron associated mechanism .lorrotating the blow-pipes when above the mold apron and for admitting airunder pressure to the blow-pipes at such time. 2

While a i'nechanical connection is shown in the drawings asexisting betweenthe two systems in a drive mechanism, such namedconnection merely exist for convenience in causing an absoluteuniformity of motion in the two systems, and could be replaced by anindependent drive for each at the systems provided the prime motorsthereof are such as to maintain a regular n and identical speed in thepa rts' dr1ven.

The blowing system, as before stated comprises a plurality of supportsmoving in a non-circular closed path in a horizontal plane, a part ofsuch path being a tangent,

15 or straight,- combined with mechanism whereby air under pressure isadmitted to the blow-pipes carried on such supports during all or partof their travel on the tangent, and jwhereby the blow-pipes are rozotated on such part of their travel. Thesupports may describe any desiredpath in additlon to the tangent before named but-tor convenience inconstruction, their whole path preferably consists of two. tangentsThatsupports in which the blowing takes place, will for convenience bedesignated herein as the blowing path, although the blowmg may 0 notcontinue during the entile travel in'suclr path. The blow-pipe supports1n the embodiment shown project horizontally from the face of an apronwhlch taco 1s vert'i -al, the apron being carried by sprocket-wheelshaving vertical axes and rotating in hori zontal. planes.

The mold system travels in a vertical having the .upper part ot-its runl or a tangent and beneath the blowll hilc the the remainingpart of therun character oi. the mold return portion connected at its ends to thegsj upper straight run (which is herein called the blowing run) bycurved paths. In the embodimentot the invention herein shown the moldsystem comprises an apron having.

a horizontal face. carried over opposite sprocket-wheels. the axes ofwhich are horizontal, and which rotate in vertical planes.

The apron has proiectiug from the face thereot sectional molds. whichare preferably of the paste type and are opened byv suitable springs.tllli'l closed by mechanism.-

arranged adjacent to the blowing run, and which on their lowerhorizontal rim inay be wetted by traveling through a suitable bath. forwhich reason the lower-run of the molding system-is herein called thewetting run. The two systems with the sprocl sets by which they arecarried. are mounted in a suitable rigid tramebr structure which issvelt contained in tlmt'itcontains within itscl'l the proper driving;mechanism and air v. r v

yjeltem is not essential for conynience 1t preterably consists of astralght supply; and one of thesystems as a whole (in the form shown themold system) is movable vertically to accou'nnodate the machine todifferent heights of molds and dift'erent lengths of blow-pipes.

The framcr llhe supporting mechanism consists of an upright t'ran'ie.preferably composed of three castings, and an extension for the supportof the moldingsystem.

The lower casting 1 'ot the trame constitutes .a base and is providedwith legs 3 and connected by a bed l. and carries a box-5, forming ahousing rmthe driving mechanism and air-compressor, which in turnsupports the bracket (3 carrying the vertical shafts of the blowingsystem. The'legs of the base casting rest upon,girders T,whichproject'outwardly therefrom to what may. be called'the front of themachine, and sup? port at their outwardly projecting ends" standards 8.i

T he mold s;2 st0m.-'-l he horizontal shafts I 9 and 10 of the moldsystem are supported 1n and held apart by radius bars 11, one on bymeans of clamp nuts 14;. whereby "the height of the radius bars may bechal'iged by looscningthe nuts and sliding the studs within the slots,and as a means whereby the radius bars and parts carried thereby may beeasily raised and lowered to etfect this change. a system of toggles isprovided.

.This system consists of a vertical toggle 15 for each end of eachof-the radills bars. and apair of horizontal toggles 16 forstraightening the links thereof. The upper links 17 otthe verticaltoggles have their upper ends iournalcd on the horizontal shafts 9 and10 and the corresponding lower links 18 are in the form of arms proectetl trom shafits 1?) journaled in bearings 20 carried on the gird--ers T. the shafts 19 pro ectmg beneath the run or the mold-apron.whereby the'toggles '15 at the same end. but on opposite sides of therun. are caused to move in unison. The vertical toggles each breaktoward thecenter and are thus oppositely faced, and for the purpose ofcontrolling their movement.

the upper links 17 thereof on each side of the apron are connected by ahorizontal toe gle 10, the knucklesof the horizontal toggles on theopposite sides of the l'l'lllbtflllg connected by a trunnioned nutQl.extending above the radius bars, and receiving between them a wormcarried by a cross plate 23 extending "from one bar to the other. and

provided with a hand wheel :24, whereby the These studs are containedmesses vertical position of the nut may be altered and thus thehorizontal toggles straightened or broken, which will cause acorresponding change in the position of the vertical log 'gles, and thuscause the radius bars to be raised and lowered in. unison, and maintainthem horizontal during such change in elevation.

The horizontal shafts l) and 10 have mounted thereon between the radiusbars, sprocket-Wheels and 26, respectively, over which travels themold-apron 27, consisting of a number of elements journaled' andconnected together by axles 28, which have upon their projecting ends,supporting rollers 29. Sollars surround thejaxles'inside ot'. therollers, the teeth of the sprocket-wheels en gaging the collars, whilein order to more accurately guide the apron on the tangents, thesupporting rollers are preferably curved and run on tracks 31 and 32having a rounded upper contour to conform thereto, the tracks beingsupported from the radius bars, the'upper track 31 by brackets 33 andthe lower track 32 by links Each element of the mold-apron consists of aplatform 35 carried on a pair of links 36 and by preference the platformand links are made integral by stamping from sheet metal, the linksbeing formed by flanges struck down from the side edges of the platformand extending slightly beyond the ends of the same. The links thustermed are at one end bent in toward the center to a distance equal totheir thickness and are bored at each. end to receive the axles 25, thecollars 30 surrounding the axles serving to hold, the, platformscentrally thereon a to space the rollers 29 at a fixed distance on each.side of the platform.

Located on the. platform of each element oi the apron is a sectionalmold 237, consisting of twoparts wh h are pivot-ed by a vertieal pin 38extending through forwardly projecting arms 39 on the mold p:1rts,'ax1dcarried by a. bracket l0 arising from the lront end o the platform lfnacoiled spring 4-1 encircling the pin and having its opposite endsengaging the arms of the opposite mold pill! and tending to throw themapart the limit of movement ol the parts being such as to permit, whenthe molds are fully open, the blown article to be moved from theinterior cavity of the mold by a movement in the plane of division olthe mold. ElCll .roold part has upon. its base. at the rear thereol, ancar 42, which. slides between the platform of the element on which it ismounted and a plate -13 supported a slight distance above the same. theface. or the plate adiacent to the mold being struck from the centeraround which the mold parts move in opening. l'l'hile the molds are allsimilar and are generically designated in the drawing by the referencecl'uu'aciersi 15?, l have which bosses with coii]'ici-at-- blowing run(it the m ld-api 'on, constitute means for closing the molds on suchruns and holding them closed. The plates 43 are carried by brackets ll,arising from the upper n'mld-apron track 31, and having hori zontalextensions l-T, on which the plates rest, the parts being; looselysecured together by bolts l8 passing: through slots -ll) in the plates.The plates are normally pl'UjcCtt-ll toward the center of the apron bymeans of spriu s 50, which are adjustable by screws 51, the springscausing the. plates to 'l'ully close all the molds as they passtherebetween, even though they should vary somewhat in size. Each of themold parts is prevented from passing, the center line of the moldapronby means of a stud 52 carried on the platform of each mold element.Those mds of the plates which are toward the poiut'at which the moldsenter the blowing run have inclined faces 5?). up which the bosses onthe molds slide to ellect the closing of the molds, the opposite ends ofthe plates terminating abruptly. whereby the molds are permitted to bequickly opened at that point by their springs l1.

As by preference the molds are paste molds and require wetting betweenblowing a water tank Til is supported from the lower mold track 32, thecontents of the tank being if desired. hcated'hy means of a steam pipe55 projecting therein.

lt will be noted that the horizontal shafts and 10, the sprockct-wheels25 and 2ctheremi, the upper and lower mold tracks ill and 3:5 and themold-closing plates 45 supported from the former, and the water tankE'l-l supported from the latter are all carried by the radius bars llandmay have their vertical positions altered therewith bv the toggle systembefore describedu i The Mow-pipe ag istcmtilhe blow-pipe system revolvesaround two vertical shafts 56 and 57 placed at a distance apart slightlygreater than the distance separating the horizontal shafts 9 and 10, thevertical plane in which the vertical shafts are located being displacedlaterallyto one side ol the center line of the blowing run of the moldsystem.

The vertical shafts carry upper sprocketwheels on and on respectivelyand lower sprocket-wheels (SO and (ll respectively, and are supported attheir upper ends in bearings located in the opposite horns 62 and (33respectively of each casting. Around the two upper sprockets extends abelt 64; formed by a plurality of elements, each consisting of pairs oflinks 65 and 66, one end of each link being brought toward the centerline of the belt formed thereby to a, distance equal tothe thickness ofthe link itself. A similar belt 67.11aving the described constructionalso passes over the lower sprockets and the two belts .areconneeted andformed into an apron by axles 68' extending from and above the upperbelt to below the lower belt, the projecting ends 69 of the axles beingbifurcated, forming supports for wheels 76, the lower Wheels travelingupon a track 71, carried on brackets '72 from the box casting, and lyingbelow the path of 1 motion described by the belts, and the upper wheelsupon a similar track 73 carried by brackets .74, from the top of thebracket casting 6 and by brackets 75 sleeved upon the upper end of thevertical shafts 56 and {)7 above such path of motion. The lower tracksupports the apron thus formed and also guides it; on its tangent runs,but as the upper track p erely the latter function, it is 'onlyocoextcnsive with the tangent runs.

, The links'of each of the belts are separated from each other bycollars 76 surrounding the axles and Ewith which the teeth of the vsyn'ocket-wheels engage.

A brackets 85 arising from the-i 1 stems has its lower end terminatingin a hollow chuck 80, the interior of which is conical jand. preferablypolygonal and has a pack ng liet its smaller end. The chucks whichntinued down *ardl-y by conical deto R82 are pro ected downwardly byroiled/s rin 's S3 inter )osed between their upper facesand the lowerends of the bushing. The tubular stems '79 above the bush ings arereceived in tubular extensions 84, in res 'icct to which theygirecapable of rotation and vertical motion; such extensions being guidedand held lrigir' v in place by per faces of the upper links (15 ofthevrbelti f I Between the cars 77 ontl' evtwoili'nks the bushings 78have each sera'iredfithereto a friction-driven pulley 8(3. and betweenthe webs of the links a friction-driving pulley ST is mounted in slotstransverse-tothe length of the links. Adjacent to the -blo,w-

in'g run of the apron and inside of and a-tf the level of the upper beltthereof is located a friction plate 89 supported from the brackets Hcarrying the upper track, the plate being mounted from the brackets insuch a manner as to permit a slight move link of said belt centralportion against the edge o't thc ment to and from the plane of motion ofthe belt, being projected toward such plane by leaf springs 90interposed-between it and the brackets.

Each of-the lower: link iif the upper belt has lugs 91projectinginwardly from the middle thereof, the ed a orl-saa lugs beingbent down to torm'bearings 92 for a pin 93 on which is pivoted, o-rankarm 9-1, the horizontal member 95 which projects utwardly in respect to'theglinks and is pressed downwardly by a coiled spring 96 interposedbetween it and the lower surface of the web of the link, the verticalarm 97 of the crank projecting upwardly through a slot 98 formed in thelug and carried on this upper end, a friction roller 99 so located. thatit will be by the travel for the apron brought behind the frictioniplate89, clamping it against the frictiomdtrvihg pulleyaST, and at the sametime pressing the frictiondriving pulley against the friction drivenpulley $6, whereby ,the rotation imparted. to the former as it rollsalong the plate, due to the movement ofthe belt, will be imparted to thelatter, thus rotating the chuck splined therein.

The lower belt at points vertically below the projections of the upperbelt carries blow-pipe supports 100, these supports consisting of plates101 iz'lstened to the lower and projecting outwardly therefrom or of.projections on the links themselves. At points vertically below'thcchucks carried. by the upper bolt, the plates are provided with slots10! the ends of which open rearwardly in respect to the direction oimotion of the apron, The slots are located in the angle of an oil-setl(l8 formed on the plates. so that the inner walls oi" the slots arecontinued for some distance in the rear of the mouths thereof by theouter edges ill-l of the plates 101, thus atl ording guides l or theinsertion of the re movable blou=pipes 105, the lower ends of which, theoperator, by thus pressing the plate at the rear o'fsaid oil-setportion, will lorate iii'tlu' plane of the center ol' the molds.

Above each plate and adjacent to the slot is pivoted an arm 'llllipressed by a spring 107 in a forward direction and. proridml on itslowerflacc with a roller 108, whereby the blow-pipe when inserted in theslot will be held by a resilient pressure toward the fora ward endthereof, and at the same time the friction created by the rotation. ofthe blo\\'- pipe will be taken up by such roller. For the purpose oitaking up friction between the blow-pipe and the plateia roller 109 is 1located at the closed end otthe slot. Each l ilbw pi p c si'ipporthasrece v s, 110 formed in the side walls of the slot l'l'ieitein in whichare pivoted Vertical flanged rolle 's l l 1. upon r the 'icriphcraltreads of which the lower face of collars 119', preferably adjustablysecured on the rcn'iovablc blow-pipes are adapted to rest. the peri'ihery of such rollars setting within the ilangeso't such verticalrollers. By this construction the we ht oi" the blow-pipe carried by thevi-a-tical rollers, and-rotation 01" the,- later is made :asy. due tothe elimination of slidihg friction, while the horizontal. rollers, andthe i'lan'g'es of the vertical rollers center the blow-pipes againstlatcral strain.

ll'hile the removable blow-pipes are all similar, and are designated. inthe drawings by the reference character 1.05, l have for the purpose ofidentifying the several blowpipes in the dili'erent figures,.furtlmrspecialized the designation thereof by alphabetical exponents.

It will be seen that the hlmvpipe apron like the mold apron. consist-sof a number of elements. each oi these elements consisting of a sectionof the upper and or the lower .l'ielts with the connecting axles andwheels,

with a blow-pipe chuck carried inv the upper belt, and blow-pipe supportcarriell on the lower belt. the parts being so located that theblmwpipes carried by the apron will be caused by the travel thereof onthe blowing run, to move in the vertical plane in which are located thecenters of the molds. and so that the axes of each blow-pipe carr .l bythe chucks and blow-iipe supports will coincide wncn the mold apron and"the belt apron are driven. at the same speed. with the of thecorresponding molds between the points at which the molds close andopen.

Located centrally on the upper end of the bracket casting; is the airdistributing box 113.

This consists of a cylinder Ill forming a bearing for a sleeve 11:")having upon its lower end a beveled gear 116 meshing with acorrespoiuling pinion 117 upon a horizontal shaft 118 mounted on onehorn (32 of the bracket casting 6, such horn being; depressed to permitthe horizontal shaftto lie below the upper sprocket 58 on the verticalshaft 50 by which it is driven through a beveled pinion ill) and abeveled gear 120, the gearing being so proportioned that the sleevemakes a complete-revolution for each complete revolution of the apronbelt due to the rotation of the sprocket. The sleeve has around itsupper part a flange 121 in which is bored. a number of equally spacedperforations 122, equal in number to the chucks carried by the apron.iho outer ends oil these perforations are tapped to receive couplingsconnected to air-pipes 123, the oppositeends of which are connected tothe tubular extensions 8-1, of the chucks. As a part of each of theair-pipes necessz rily flexible due to the fact that they de scribe acircular path, whereas the (fllIlCKS to which they are attached In ve ina noncircalar path, the pipes are supported above oi the chucks by meansof spider ironi a central hub 125 flange 121. The arms are ii'rom theircentral ring and ends collars in; carurine rounded ldUChs l2? over whichthe flexible pipes lead. in the .drawings these unaided supportingblocks are shown in the torm of pulleys but this is not cssci'itial asicir ii'unction is not to permit a travel of in pipes thereover, but ismerely to guide be curvature thereof and prevent kinking. The arms areof a length approximately equal to the arithmetical mean of onehalf ofthe major and minor diameters of the figure described by the path of theblowpipes, and thus alternately have their ends located within such pathand beyond the san'ie so that at times the flexible pipes projectinwardly from the ends of the arms and at other times project outwardlytherefrom, in leading to the chuck extensions.

Due to the different paths described by the ends of the arms and chucks,the relative distance between such parts when projected on a horizontalplane varies and for the purpose of reducing to a minimum the slack ordifference in length produced thereby, the

arms terminate at some distance above the top of the chucks whereby thedistance between the chucks and the ends of the arms is not merely thehorizontal projections of their displacement but is the hypotenuse of atriangle, the base of which is such displacement and the altitude ofwhich is the elevation of the ends of the arms above the chucks. is thehypi'itenuse of triangles of equal height and of different basesrelatively small in comparison with the height vary but slightly. itwill be seen that by this means I have provided for a substantiallyuniform distance between the ends of the spider arms and chucks.

The upper end of the cylinder 11-]: is slightly reduced in diameter toreceive a collar 12% which has a slot- 12!) therein, and the cylinderitself has on the side adjacent to the blowing run a port or chamber 130formed therein which is closed by a plate 132 suitably tapped to receivean air supply pipe 13?) which leads therefrom through. the center of thebracket casting to the air pressure erpializing, tank or reservoir 134-.which may be located in the base of the machine.

The perforations 122 in the flange 121 are located in the saint:horizontal plane as the portlfli') and slot 3'39 in the collar, but donot extend to the inner face of the sleeve, being connected therewith bynarrow slots 135, the thickness of which is several times less than thatoi. the diameter of the perforations. and which bisect the perforationsfor a length equal to several diameters thereof. The collar does'notrotate in respect to the cylinder 11% in the operation of the machine atthe time when the chucks connected there with by its air-"distributingpipe and on the blowing run of the belt apron. During the movement ofthe chucks on such run air will flow through the chamber or port 130 inthe cylinder, slot 129, and through the slots 135, etc. to the chucksconnected respectively therewith, and will thus enter the interior oftheblow-pipes which are carried by such chucks and thus inflate the glasscarried by the blow pipes. As the collar is removable it may be changedfrom time to time to accommodate the slot therein to the character ofthe article blown and demands thereof for different "air-pressures andair. regulation. By preference the slot 129 in the collar will betriangular in shape, its narrow end being that end which. is firstuncovered by the slots 135 in the sleeve in the rotation of the latter,whereby the pressure created in the blowpipes will be graduallyincreased; and by preference this triangular slot will terminate at itsnarrow end in a cross slot 137 whereby a comparativelystrong initialblast of air will be created in the blow-pipes.

It is obvious that by altering the circum- 7 ferential position of thecollar 128 the initia tion and termination of the blowingoperation inrespect to points in the blowing path of the blowing apron may bevaried; and that by replacing one collar by another any desired orrequired variation in the air sup ply may be obtained.

The sleeve is held upon the head by means of a bolted flange 138, andfor the purpose of strengthening the spider arms rgainst the stressesdue to the weight of the distributing .pipes' their radial portions arepreferably connected by a hormontal annulus 139, which not only servesto prevent side displacement thereof but also to balance the weight ofone arm against that opposite thcreto.. V Drz'i' im mcchanz'sm1 suitablemotor 140, preferably electric, is contained within the interior of thebox casting and drives through a horizontal counter shaft H1, and wormand speed reducing gearing 142, the gear 14:5 upon the lower end. ofthat vertical shaft 56 which carries the sprocket wheels around whichthe b1 \ving-apron passes when leaving the blowing run. which shaft forthis purpose is continued through the b ticket-casting and has a footingin the bottom of the box casting. As the other horizontal exter n i0 e gng a v 151 in the slotof the beveleu pinion holds the latter in. meshwith the go: and guides it to preserve such mesh, radius bars and Ni iithem the horizont....,. shaft 9 are raised and lowered.

A suitable air-compressor is locat 'd in the box. casting and. thepiston thcrcor 2a driven by an eccentric mounted on the horizontal.countershaft l-ll, the compressor being connected with the air tank 13by a suitable pipe In the operation. of a machine so con structed, theoperator having gathered and marvcred a batch of glass upon a blow-pipeplaces the upper end of the latter in one of the chucks, the coneshapeddeflector 8L- there on, serving as a guide forhi n in t! a movement. Hethen slips the intermediate part of the blow-pipe below the collar th onintd'the, blow-pipe support, the strai ht edge 104: of the supportserving as a guide ter of the molds and being guided in this plane bythe edge of the support, there will exist nodanger of niarring thefinished product by touching the molds with the glass, and thus I ampermitted to load the 7 machine while running. The blow-plpehaving beeninserted in the machine the subse quent operations are purely automatic.The

movement of the mold in the blowing run causesthe closingtbercof,.\vlnle the simultaneous travel of the blow-pipe causes therotation thereof, and the air is'admitted. 'llhe' inolds-before theyleavetheir horizon tal patln'are opened by their springs. free ing thefinished article which remains suspended onthe blow-pipe and isby themovement thereof carried away from crew the mold-apron. The blow-pipewith the finished product thereon may now be reunited at any desiredpoint of travel of the blowapron.

The movement of insertion messes It will be noted that in loading amachine such as above described, the insertion of the blow-pipe withinthe mold takes place in the line of movement of the mold itself, sothattlie operator has simply to insert the blow-pipe in a straight line.'lhis is an important feature, as in any machine in which the insertionoi. the b ow-pip. is right angles to the line of movement of the mold,the operator called upon to move the blowpipe with a compound movement,that is to say, not only to bring the blow-pipe within the mold but tocenter it therein by following the mold in its movement, which ditficultand often results in the glass upon the blow-pipe striking the sides ofthe mold, thereby imparing; the finished article.

It will be noted that only one of the ver tical. and one of: thehorizontal shafts are driven,- these shafts being those located at thedelivery end of the blowing path of their respective systems. Thus thefriction and the inertia of the aprons will maintain them taut at alltimes, and as the sprocketwhcels of the two systems are by preferenceidentical in pitch radius and number of teeth, and are driven insynchronism, and as further by preference the driving sprockets of thetwo systen'i's are similarly positioned at the same time (that is to saythat the teeth thereon are similarly lo aited in respect to the blowingrun) it will be seen that at each instant the speed oi? the elements ofthe blowing-a pron in its blowing run will be the same the speed oi themerits oi? the molding-apron on such run.

\Vhile the pitch radius of the sprocket wheels of the two systems andlengths of the elements of the belts thereof are preterably identical,it does notlollow that this should be true of the number of elements ineach system. On the contrary it is advisable, as shown 'in theaccompanying d'awings, to use a greater number of elements in theblowing system than in the molding system, so that the tai'igent of theformer is oi greater length than the tangent of the latter. as therebythe molds are raised to the level of the lower ends o1 the blowpipes,and are lowered from such level while thecorresponding ljilow-pipes aretraveling in their straight path. After the molds have fallen below thelevel of the articles carried-by the l' low-pipes, the latter will moveupon their circular path and out of the vertical molding plane withoutcausing them to interfere with the molds, which would be the case if thenumber of elements in the two systems were the same or if the shafts layin the'same plane, in the latter case the blowpipes would start theirmovement in a circular path in a horizontal plane at the same time thatthe molds start to move in a circular path in the vertical plane, theresult of which would be that the blown article would strike the tops ofthe molds before the latter had fallen suli ciently to clear them.
